Thermal conductivity and adhesion strength effects were studied for thermal barrier coatings (TBCs) with different particle sizes, YSZ content, time, and temperature curing. The study involves three stages. The first step focuses on the characteristics of YSZ/polysilazane as the TBC, which is characterized using Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FTIR), X-Ray Diffraction (XRD), and Thermal Gravimetric Analysis (TGA).

This study presents the novel application of AlO coated with TiO as a thermal protective layer for CFRP substrate. Initially, the CFRP substrate underwent a protective treatment involving the application of AlO as a middle coat, followed by a further protective layer consisting of TiO as a top coat.

However, the pathomechanism of NEC remains elusive. This study aimed to analyse the risk factors for NEC among preterm neonates in East Java, Indonesia.

There is no factual data about the prevalence in Indonesia. It is common that neonates with suspected hereditary spherocytosis are not diagnosed or treated adequately in developing countries such as Indonesia.

Therefore, it is important that pediatric residents in Indonesia acquire adequate knowledge of hyperbilirubinemia management. This study aims to determine the pediatric residents' knowledge on hyperbilirubinemia management, whether they follow recommended guidelines, and whether differences exist between five large Indonesian teaching hospitals.

In order to reduce the incidence of the disease, a protocol on preventing, screening and treating ROP was published in Indonesia in 2010. To assist the practical implementation of the protocol, meetings were held in all Indonesia regions, calling attention to the high incidence of ROP and the methods to reduce it.
